Another image using the photo-to-line art technique I described in a previous post.
The predominant focus in the neurobiological study of memory has been on remembering (persistence). However, recent studies have considered the neurobiology of forgetting (transience). Here we draw parallels between neurobiological and computational mechanisms underlying transience. We propose that it is the interaction between persistence and transience that allows for intelligent decision-making in dynamic, noisy environments. Specifically, we argue that transience (1) enhances flexibility, by reducing the influence of outdated information on memory-guided decision-making, and (2) prevents overfitting to specific past events, thereby promoting generalization. According to this view, the goal of memory is not the transmission of information through time, per se. Rather, the goal of memory is to optimize decision-making. As such, transience is as important as persistence in mnemonic systems.
This is a fancy way of saying, just think how hellish it would be if you were unable to forget any face you had ever seen on BART.
Recently I’ve been experimenting with a technique for converting photos to line art, which can then be colorized. (I don’t claim this technique is original to me, but I’ve been refining it for my own purposes.)
The essence of the technique is the conversion to lines, using the color dodge and multiply blend modes. In the artwork above, I started from this photo:
